Auckland baggage-handling technology firm BCS says its annual revenues have jumped by about $60 million to reach $140m.

Chief executive Patrick Teo said the privately-owned firm was finalising the numbers.

BCS now employs 400 staff, up from 330 in October last year. The company has just completed its largest-ever contract, a $40m project at Malaysia's Kuala Lumpur International Airport, and Teo said many of its wins now exceeded $25m in value.

Marketing manager Marc Michel said last year that business was booming in Asia because of the rise of low-cost airlines, a growing middle class and a string of ferry disasters that had encouraged more people to travel by air.

Teo said BCS had won an "internationally-contested bid" to build a parcel sorting system at a A$170 million facility that Toll Group has been constructing in Sydney.
